1 Claim.

The present invention relates to apparatus for impregnating water, suchas that used in carbonated beverages, with CO2.

One of the objects of the invention is to provide a carbonator which,with a comparatively small water container, may impregnate acomparatively large amount of water in a relatively short period oftime. To this end, in the present invention, I provide a container inwhich a large volume of C02, commonly referred to as gas, is maintained,preferably under pressure, and the water to be carbonated is deliveredwithin this container in the presence of the gas, in a fine spray. Inpassing through the gas, this fine spray of water will absorb a, largeproportion of gas. This initially carbonated water is againre-circulated through a sprayer which delivers the water a second timein the form of a ne spray, the water passing through the gas, therebyabsorbing the gas a second time, so that eventually it has absorbedabout all of the gas it can take up.

For the purpose of disclosing my invention, I have illustrated anembodiment thereof in the accompanying drawings, in which:

Fig, 1 is a side elevation of carbonator embodying my invention,portions thereof being shown in section;

Fig. 2 is a plan view of for the container;

Fig. 3 is a side elevation thereof;

Fig. 4 is a plan view of the container, with the top removed; and

Fig. 5 is a detail section of one of the spray heads.

, In the embodiment of the invention illustrated, I provide a base I onwhich the various parts of the carbonator are adapted to be mounted.This base is provided with a hollow supporting standard 2 having a top 3on which is supported the cylindrical container 4. This container restson a bottom closure plate 5 and is secured to the standard 2 through themedium of cap screws 6 passing through a ring 'I on the container 4 andinto the standard. A suitable packing ring is interposed between thebottom edge of the container cylinder 4 and the bottom plate. The top ofthe container is closed by a cover 8 secured to the container throughthe medium of bolts 9 passing through the cover and through a clampingring IIJ on the cylinder 4. A suitable packing ring is interposedbetween the top edge of the cylinder and the cover plate 8 to insure atight packing. This container has arranged therein a plurality,preferably four in number, of spray heads which are disposed at the topof the cyl- Ainder 4. Two of these spray heads II and I2 which may bereferred to as the initial spray heads are mounted at the tops of a pairof branch tends Yto hold the heads more or less rigidly in position.

On the underside of the bottom plate y5, I mount a connecting unit 2Iwhich is preferably in the form of a single casting provided on its topsurface with an annular flange 22 to provide a recessed surface intowhich a suitable packing `may the connection casting be tted. Thiscasting is provided with bolt-receiving openings 23 adapted to receivesecuring bolts- 24 passing through the bottom plate 5 and into theopenings, whereby the casting will be secured to the under face of theplate 5, surrounding an opening, corresponding in general in contour, tothe casting. This casting is provided with an inlet extension 25screwthreaded at its bottom to receive an elbow 26 into which isscrewthreaded the infeed pipe I5. This infeed pipe I5 is connected by asuitable conduit or pipe 21, through the medium of the elbow 21 and aconduit 28 with a reciprocating pump 29 mountedl on the base I which hasan intake opening 30 connected with the source of water supply, whereby,the Water tobe carbonated may be delivered by this pump to the cylinder4 through the primary spray heads I I and I2.

The inlet extension 25 communicates with a coupling 3l secured on thetop of the casting 2I and this coupling is provided with branchesreceivine, respectively, the threaded ends of pipes 32 and 33 connected,respectively, through the medium of suitable elbows, with the secondarysupply pipes I8 and I9 leading to the secondary spray heads I6 and I'I.This extension 25 is provided with an inlet opening 34 connected by asuitable coupling 35 to the discharge side of a centrifugal pump 36likewise mounted upon the base I. 'I'he intake side of this centrifugalpump is connected by a suitable conduit 3I to an outlet 38 opening intothe bottom of the cylinder I4. This outlet 38, as shown in Figs. 2 and3, is adapted to have connected thereto the pipe coupling or conduit 31,so that, as the water ows through the outlet opening 38, it willdischarge into the the cylinder 4 having a reverse bend 44, so that thegas or CO2 will be discharged into the cylinder near the top.A The gasinlet 4I is connected with a suitable CO2 supply, lin any desiredmanner,and preferably the.- gas is maintainedtin the cylinder 4 under pressure.

The fitting 2l is also provided with an air disn charge opening 45having secured therein an air escape pipe 46. This pipe extends to thetopvof the cylinder 4 and is provided with an escape 'head 41T arrangedover a bailleplate 48;. Prefer'- ably, this air discharge outlet`45connected hy a suitable conduit or pipe 49'; with the water inlet checkvalve. on the discharge side`v of the reciprocatingipump, so thatl asthis` valve isoperated', a snift' valve in the. conduit 49 is' openedito permit discharge of air from the cylinder to atmosphere. y t

A water discharge'y outlet 50 is-al'so provided in the fitting 2|? and'Ythis` discharge outlet isy connected through` a suitable valve with thedischarge fitting or discharge pipe of' the carbon'ator;`

In operation, the water, through the medium of the reciprocating pump`29, Vis drawn-from the source' of supply and delivered through the pipeT5 'and' the two branches I3, tothe spray heads l'f' and Il?. By thesespray' headsi the water is brokenfup into an extremely ne spray and inthis" sprayed form,v falls through the atmosphere of' C02 contained inthe container 4. As a result of the breaking' up ofthe water in thisextremely fine spray, considerable of the airis released from the wateryand, at the same time, the water absorbs alarge quantity of CO2 in thecontainer 4. This water, which is fairly we11 permeated witlfi gast-bythe time it reaches the bottom of' the container, then flows through thedischarge 38 into the centrifugal pump 36 which again delivers the waterthrough the fitting 25 to the two secondary supply pipes i8 and i9 andthrough the secondary spray heads I6 and l1. The water is thus againbroken up into a ne spray and this fine spray, in falling through theatmosphere of CO2 contained inthe container 4thef-water completelyabsorbs the C92rv sov that it ifs fully saturated. This saturated water,of course, may be drawn ,off from time to time, as needed, through thedischarge opening 50.

Fig. 5, I have illustrated a detail section of one of the dischargeheads. As each of the heads ofthe same construction, only one issufficient. This headcomprises a hollow base 5I connected by a couplingmember 52 with its pipe and this-base; on its interior, has a lug 53adapted, to receive a stem 54 upwardly extending. Surrounding this stemis a coiled spring 55 which rests on the lug 53. 'A cap 56 covers the.topL of thisY springa'nd this cap is adjustedlth-rough the medium ofsuitable set screws 58 soi that! the spring may be com-pressed toi thedesired' degree to thereby vary the sizeof thespray openingsformed''between the coils of they springs.
